JSON API
A fast, fully-local JSON and CSV toolkit: validate JSON (with a clear error message, type and size), pretty-print and format it (with optional deep key-sorting), minify it (reporting bytes saved), and convert between CSV and JSON — RFC-4180 CSV parsing with automatic value typing, and JSON arrays to CSV. Every endpoint accepts input via the query string or the request body (up to 1 MB). Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for data pipelines, ETL, webhooks, config tooling and developer utilities.
